Pulse test bench, also known as pulse testing machine, is mainly used for factory inspection of the following parts: Automotive hoses: steering pipe, brake pipe, air conditioning pipe, fuel pipe, cooling water pipe, heat dissipation hose, warm air hose, air filter hose, turbocharger system hose and engineering hydraulic pressure hose; Aviation hoses and manifolds; Pulse test of other hard pipes or joints and automobile brake pump, radiator, oil cooler and cylinder block. Oil delivery hose and assembly, brake hose, water tank hose and assembly, water tank, oil tank, condenser, evaporator, liquid storage tank, filter, etc.
Functions and features
1. Multi station, multi-channel test can be carried out at the same time without mutual influence, and the experimental data and graphics are automatically recorded and saved in the computer;
2. Imported components are adopted for the parts, which ensures the accuracy and stability of the testing machine from the control principle and the quality of electrical components;
3. The test software is mature and stable, which can set experimental parameters and customer information, display the pressure time curve, ambient / medium temperature, pulse times, pressure value, etc. in real time, and print out;
4. In this technology, the accumulator is used to supplement the pressure, which realizes the passive control, reduces the working time of the motor and the pressurization system, improves the reliability, stability and service life of the pressurization system, and ensures the pressure accuracy at the same time;
5. The machine has the function of overpressure and overload protection, and has the function of equipment pressure calibration;
Technical parameters:
Equipment function: carry out pressure pulse fatigue test on low-pressure pipeline and assembly to assess its fatigue life and fatigue failure form; Provide safe and effective protection measures, fault diagnosis and reliable data; And can meet the requirements of special experiments
